## Changes things (4)

Creates or changes something that can be changed back. Claude Code: ask.

### `calculate_order_quantity`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when someone asks how many units to order, given demand, lead time, stock on hand and on order, and supplier rules such as MOQ, case pack or a minimum order value. Sizes the line the way Forthcast sizes a purchase-order line and lists every rule that changed the quantity. Works without a connected store.
```

### `calculate_reorder_point`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when someone asks how much safety stock to hold or at what stock level to reorder a product. Give a daily demand history (best) or an average daily demand with its variability, plus the supplier lead time and a service level. Returns safety stock, lead-time demand and the reorder point with Forthcast's formula and assumptions. Works without a connected store.
```

### `forecast_demand_series`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when someone pastes past sales numbers and asks what to expect next month, next quarter or next season. Takes 3 to 365 monthly, weekly or daily totals (oldest first) and returns the next periods with an 80 percent range, the model used (Holt-Winters seasonal, damped trend, Croston for intermittent demand, or moving average) and why. Works without a connected store.
```

### `score_inventory_health`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when someone shares a list or CSV of products with stock and sales rates and asks which need reordering, which are overstocked, or how healthy the inventory is. Up to 500 rows. Applies Forthcast's urgency bands (Order now, Plan ahead, On track, Excess, No demand), reorder points, suggested quantities and inventory value. Works without a connected store.
```

## Only reads (7)

Looks things up and changes nothing. Claude Code: allow.

### `explain_inventory_metric`

- The name "explain_inventory_metric" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when someone asks what an inventory planning term means or how Forthcast calculates it: safety stock, reorder point, days of cover, urgency bands, service level, ABC class, EOQ, order quantity, fill rate, on-time rate, lead time, intermittent demand. Works without a connected store.
```

### `find_inventory_items`

- The name "find_inventory_items" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the merchant wants a bounded list of their items filtered by urgency, assigned supplier, or Shopify vendor, such as all excess items or a supplier's critical SKUs. Requires a connected Forthcast store; the assistant will prompt to sign in.
```

### `get_inventory_item`

- The name "get_inventory_item" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the merchant names an exact SKU and needs its live stock, forecast demand, days of supply, reorder point, suggested quantity, supplier, or open-PO coverage. Requires a connected Forthcast store; the assistant will prompt to sign in.
```

### `get_inventory_overview`

- The name "get_inventory_overview" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the merchant asks for a broad inventory health check, an executive summary, their urgent/excess/no-demand counts, inventory valuation, or current PO workload. Requires a connected Forthcast store; the assistant will prompt to sign in.
```

### `get_reorder_recommendations`

- The name "get_reorder_recommendations" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the merchant asks what to reorder, how much to buy, or which critical/warning items need action. Quantities reuse Forthcast's live lead-time, MOQ, case-pack, open-PO, location, and supplier minimum-order-value logic; this tool does not create a PO. Requires a connected Forthcast store; the assistant will prompt to sign in.
```

### `get_supplier_performance`

- The name "get_supplier_performance" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the merchant asks how suppliers are performing or wants rolling 24-month on-time rate, fill rate, actual versus promised lead time, spend, or invoice price accuracy, plus current open and overdue purchase-order counts. Requires a connected Forthcast store; the assistant will prompt to sign in.
```

### `list_purchase_orders`

- The name "list_purchase_orders" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the merchant asks what is ordered, drafted, open, partially received, received, cancelled, overdue, expected, or associated with a named supplier. Results are grouped by PO; this tool does not approve, receive, cancel, or otherwise modify an order. Requires a connected Forthcast store; the assistant will prompt to sign in.
```
